The lblock is latter any articles to be heated such as cookf "'50 mounted in a -hearth structure 103 built upy ing pots or. for fully coveringthe heat 'transme li U mitting face 102 when the heatingv apparatus is out of' use.

The heat-ing apparatus just described constitutes a large cooking stove for restaurants and the like. The block m may be heated by different heat sources as may be required each of such sources by itself heating the block rapidly. Of course the block may be heated by several heat sources simultaneously. The size of the block has to be selected according to the existing conditions.

In the heating apparatus shown in Figs. 3 to 5, a; is a block tor instance, circular in shape made of some heat conducting material which encloses a gas tight and pressure tightchannel system. This channel system consists of the annular channels 301 and the radial channels 302 communicating with each other at their points of intersection.

Into the channel system is lled onceforever, a heat transmitting` agent whichv in the temperature limits Within which the accumulated heat is utilized, is in the state of saturated vapor under pressure. 303 is the heat receiving` and 304 is the heat Atransmitting tace of the block fr. The block is mounted in a base plate 305 of heat insulating material and covered by a plate 306 of the same material. The plate 306 is provided with recesses 307 extending down to the heat transrni ting tace 304 and serving to receive cooking vessels, for instance sterilizers 308. These recesses are closed by covers 309 of heat insulating material when the heating apparatus isout of use. In the base plate, recesses 310, 311 are provided Which extend up to the heat receiving face 303 ot the block a: and serves to receivethe heat sources. In the constructional form shown'in the `recess 310 an electric heating resistance 312 is mounted Which may be connected to a source of electricity by means of plugs 313 and serves for heating the block@ electrically. The recess 311 extends dia-r metrically through the base plate 305 and is adapted tobeclosed at both ends by covers 314 and 315 oft' heat insulating' material. This recess 311 serves to receive a further source of heat in which a gas or an' alcohol or a petroleum burner 3.16 or the like may be used. In case ot a gas burner one oit the covers 315 is provided with a suitable opening for the gas pipe 317- to pass through. For facilitating transport, the base plate 305 is providezgl With handles 318.

The heating apparatus described is compact and readily portable and as at its bottom side it is closed by heat insulating material, it may be placed on any table or other part of furniture. VThe block m may be heated by a variety of sources of heat as may be required and each oi' such heat sources secures a rapid heating, but the block may also be heated by more than one source of heat at a time. The heat source 316 may also be removed from the recess 311 and utilized else--Vv Where when the block has been heated to a suitable temperature. The recess 311 is closed by the covers 314;, 315 whereby the heat accumulated in the block is kept back therein for a long time. The apparatus is more particularly suitable tor sick rooms in hospitals and the like, Where frequently at night-y boilingy Water is required for s't-erilizii-i-g orother purposes, but it may also be used for cooking purposes in general, more particularly for `cooking out of door or on the dining table itself.

Obviously instead of the previously mentioned heat sources alsoother heat sources of all kinds are available tor heating the block,

for instance, a steam heating source.

That I claim. is:

1.k In a heating apparatus the combination ot at least one metallic block having a heat transmitting face and containing thereina. system of iiuid tight'channe-ls adapted to be filled once and for all with a temperature equalizing medium, heat insulating elements adapted to coverI the said heat transmitting tace, a heat receiving face on said block, a

heat insulating structure covering the said heat receiving face of the block and divided into compartments open` to the said heat receiving face and different sources of heat located in such compartments.

2. In a heating apparatus the ycombination of at least one metallic block having a heat transmitting face and containing therein a system ofV fluid tightehannels adapted to be filled once and for all with a temperature equalizing medium, heat insulating elements adapted to cover the said heat transmittingY face, a heat receiving face on the saidy block, a heat insulating struct-ure coveringthe said heat receiving :tace of the block and divided into compartments open to the said heat receiving face,l heat insulating partitions sep-H arating such compartments from each other, and different sources of heat located in such compartments.

3.. In a heating apparatus the combination of at least one metallic block having a heat transmitting` face and containing therein a system of fluid tight channels adapted to be filled once and for all with a temperature equalizing medium, heat insulating ele-ments adapted to cover the said heat transmitting face, a. heat receiving face on the said block, a heat insulating structure ,covering the said heat receiving face of the block and divided. into compartments open Vto the said heat receiving face and different sources ot heat lo cated in such compartments, one of such sources being an electric heating device located at one end of the block.

Intestimony whereof I ailiX my signature.
